A new oh fluorescence signal-to-oh mole fraction conversion model formulation
In this work a non-linear model to reconstruct OH mole fraction profiles from a stand-alone experimental OH-PLIF fluorescence signal is provided. Starting from one-dimensional (1D) counter-flow flame solutions at different scalar dissipation rates and pressures for a syngas mixture, all the OH mole fraction profiles are normalized by their maximum value and made collapse into a single profile by using an exponential scaling factor. The collapsed profile is further reconstructed as the sum of a linear term and a non-linear error term.
